T0 all 10h/)mit may concern.'

Be it known that I, JOI-1N F. OCoNNoiz, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Draft-Rigging for RailwayCars, of which the following is a full, clear, concise, and exact desci'iption, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in draft rigging for railway cars.

The object of my invention is to provide a draft rigging in which the shock absorbing member and the draw bar are connected by a simple, strong and efficient means, and one of durable and cheap construction.

In the accompanying drawings forming a part of this specification Figure 1 is a side elevation partly in longitudinal section of a draft rigging embodying my invention. Fig. 2 is a plan View of the same. Fig. 3 is an enlarged detailed view showing in elevation partly in vertical longitudinal section my improved means of connecting the shock absorbing member with the draw bar. Fig. 4 is a rear end view at line 4 4 of Fig. 3. Fig. 5 is an enlarged detail plan View partly in horizontal section of my improved means of connecting theshock absorbing member with the draw bar shown partly in horizontal section. Fig. 6 is a cross sectional view on line 6-6 of Fig. 3. Fig. 7 is an enlarged Vfront end .view of the shell. Fig. 8 is an enlarged side elevation of the shell, and Fig. 9 an enlarged plan View of the shell. Y

In the accompanying drawings 10, 10 reping stop shoulders 19, 19 and 20, 20 re spectively.

21 is the draw bai' of the usualtype provided with the transverse slot 22 for the passage of the coupler key 23.

24 is the shock absorbing member cornprising the shell 25 and its contained compression resisting parts, which may be of any suitable type.

26 is the frontand 27 the rear tie plate bolted to the center sills 10, and each of a suitable width to support the shell 25 in its relciprocating movements between the center si s.

28 is the front follower and 29 the rear follower, which is integral with the shell 25.

30 is the means of connecting the shell to the draw bar` and is provided at its forward end with a box like opening 31 to receive the rear end of thedraw bar 21. At either side of the opening 31 the lateral plates 32, 32 are preferably forwardly extended, forming the wings 33. The plates 32, 32 are provided with the slots 34, 34 in alinement with the slot 32 in the draw bar, through which slots the coupler key 23 is passed. I prefer to also provide the adjacent stopafnembjers 14, 14 and the adjacent portions of tliecenter sills 10, 1G with horizontal slots registering with the slots 34, 34 so that the coupler key\`\ may be extended through them, and inserted and removed from without the center sills. The top and bottom plates 35 and 36 respectively of the member are rearwardly extended, as illustrated in Fig. 3 of the drawings, and are connected at their rear ends bythe transversely arranged annular band 37. In front of the annular band 37 and on the inner or lower side of tlie plate is provided a lug 38. A similar lug 39 is provided on the inner or upper surface of the lower plate 36'.

The friction shell 425, which is preferably a hollow cylinder in shape or circular in .cross section open at'its' forward and closed at its rear end, is externally provided near its forward endlwith an annular band 40, and at its forwardV end at top and bottom with the project-ing lugs 41 and 42. The band and the lugs 41--and 42 are suitably separated to forni the ways or slots 43 and 44 respectively, which receive the\lugs 38 and 39 respectively of the member 30, auditie ioa .g Y

band 37 of thel member 30 encireles the bandVV iic The lugs 4l and 49 are of suitable length to pass through the spaces 47 and ld between the lugs 38 and 3S) of the member 30. The member 3() is then given a quarter turn, bringing the lugs 3S and 39 within the slots 43 and 4, thus securing the member' SO to the shell 25. The member is prevented from turning from its attached position by are inwardly tapered from the periphery of the shell, and the lugs 3S and 3i) of the member 30 are outwardly tapered from the inner surface of the plates and 3G so that the lugs 38 and 3S) dovetail with the slots #I3 and 44. I prefer to core out the rear follower L29, as illustrated in Fig. S of the drawings, and to reinforce the4 shell, as illustrated at numeral 50.

I claim z, l. In a device` of the character described, alshelf'lto contain the compression resisting fparts, a draw-bar, and a member connecting` the drawbar and shell, the shell being` provided with external lugs and an annular band spaced from said lugs forming grooves or ways between the lugs and the'annularl band, said connecting,` member being,- provided with lugs dovetailed between the annular band and the lugs of `the shell.

2. In a device of the character described, a shell to contain the compression resisting parts, a dra\v-bar, and a member connecting the draw-bar and shell, the latter being provided with external lugs, an annular band, and slots between said band and lugs, the connecting member being provided with lugs `engaging within said slots and an annular a yshell arranged to contain compression re sisting` members, a draw-bar, and a member for connecting the draw-bar and shell, the

shell being provided with annular grooves on its exterior and said connecting member having lugs arranged to engage in said grooves, said grooves and lugs on the shell and connecting member forming a bayonet joint.

5. In a device of the character described, a shell, a draw-bar, and a member arranged to connect the draw-lair and shell, said shell being provided with lugs and an annular band on the exterior thereof, the lugs and band being spaced apart and thereby forming grooves therebetween, said connecting member being provided with lugs arranged to engage within said grooves, said grooves and lugs forming` a bayonet joint connection between .said member and shell.
